As a non-biologist, my understanding is SARS-CoV-2 uses it spike protein to latch on to the ACE2 receptor on cells in order to inject its genetic material into the cell.
- What would happen if you flooded a person with exogenous ACE2 proteins?
- Would the virus attach to these decoy proteins and thereby save cells from being infected?
- Would the injected proteins cause unwanted side effects?
- Has this approach to treating viral infections been tried before?
